Ball Valves
Industry-leading ball valves engineered for the world's most demanding shut-off applications. API 6D certified, precision-machined, and available in sizes from 1/2" to 56" across all pressure classes.
Ball Valve Types
Four configurations to match your application requirements — from compact floating designs to heavy-duty trunnion mounted valves for large-bore, high-pressure service.
Floating Ball Valves
Compact, reliable shut-off for low-to-medium pressure applications. The ball is supported by the seat rings, ensuring a tight downstream seal under pressure.
Trunnion Mounted Ball Valves
Mechanically anchored ball for high-pressure, large-bore service. Reduces operating torque and provides bidirectional sealing with spring-loaded seats.
Top Entry Ball Valves
In-line maintenance without removing the valve from the pipeline. Ideal for critical service where downtime must be minimised.
Fully Welded Ball Valves
Leak-proof, maintenance-free construction for buried and underground pipeline service. Welded body eliminates potential leak paths.

Standards & Certifications
Every GLB ball valve is designed, produced, and tested in compliance with internationally recognised industry standards.
Applications
GLB ball valves are trusted across critical industries worldwide — from offshore platforms to onshore refineries and everything in between.
Oil & Gas Pipelines
Upstream production, midstream transmission, and downstream refinery isolation. NACE MR0175 compliant for sour gas environments.
Petrochemical Plants
Chemical processing, ethylene cracking units, and polymer production lines requiring corrosion-resistant alloys and zero-leakage performance.
LNG Terminals
Cryogenic ball valves for liquefied natural gas storage, loading, and regasification. Tested to -196°C with extended bonnets.
Power Generation
Steam isolation, feedwater control, and cooling water systems in thermal, nuclear, and combined-cycle power plants.
Water Treatment
Municipal water supply, desalination plants, and industrial wastewater treatment requiring reliable shut-off and low maintenance.
